AI Thread Summary
The discussion focuses on the physics of airplane flight, specifically regarding lift, drag, and air resistance in glider planes. The original poster is seeking formulas related to these concepts, noting that many sources overlook air resistance. NASA is highlighted as a preferred resource for reliable information on the topic. Participants express concern over the lack of comprehensive sources that address air resistance alongside lift-to-drag ratios. Overall, the conversation emphasizes the need for accurate and detailed physics information related to glider planes.

I need help with the physics of airplane flight with lift, drag, etc. I can find a lot of information about it, but I can't find any formulas...probably because everything I've found neglects air resistance.

Can anyone provide links to sites that would help with this?

I'm looking for info particularly in glider planes, sort of like the ones the Wright Bros. flew.

Thanks for any help.
 
Science news on Phys.org
NASA has always been my favorite source for such info. This site within NASA.gov has a lot of links and should tell you whatever you need to know.

BTW, are you saying that all the sources you've found talk about lift-to-drag ratios while neglecting air resistance? Not only is that shamefull, I don't even see how it's possible!

Could you give a link, I'm curios as to how this was accomplished.
 
Sorry, I worded that incorrectly. I meant to say that I couldn't find any formulas, and the few sites I do find formulas for do so neglecting air resistance (which, just by looking at the the formulas they gave without really looking into it, simply make it Newton's Law's with different variables).

That site has exactly what I'm looking for...thanks for the help.
 
Thread 'A quartet of epi-illumination methods'
Well, it took almost 20 years (!!!), but I finally obtained a set of epi-phase microscope objectives (Zeiss). The principles of epi-phase contrast is nearly identical to transillumination phase contrast, but the phase ring is a 1/8 wave retarder rather than a 1/4 wave retarder (because with epi-illumination, the light passes through the ring twice). This method was popular only for a very short period of time before epi-DIC (differential interference contrast) became widely available. So...
I am currently undertaking a research internship where I am modelling the heating of silicon wafers with a 515 nm femtosecond laser. In order to increase the absorption of the laser into the oxide layer on top of the wafer it was suggested we use gold nanoparticles. I was tasked with modelling the optical properties of a 5nm gold nanoparticle, in particular the absorption cross section, using COMSOL Multiphysics. My model seems to be getting correct values for the absorption coefficient and...
